摘要	The kinetics of dissolution and phase transformation of 2MgO . 2B(2)O(3) . MgCl2 . 14H(2)O in water at 87 degreesC were studied. The results of liquid phases anlysized at a given time intervals and solid phases identified by IR and XRD show that 2MgO . 2B(2)O(3) . MgCl2 . 14H(2)O dissolved incongruently in water and the process was not the same at low temperature, a new crystal midproduct(MgO . B2O3 . 4H(2)O) was formed, the final solid phase was pinnoite(MgO . B2O3 . 3H(2)O). With the aid of Simplex Optimum Method and Runge-Kutta Digital Solution of differential equation system, the experimental data was fitted. The kinetic equation of the crystallization reaction was given and a mechanism of crystallization reaction was proposed.
